Castrol Aircol PD

The Aircol PD range of compressor oils are based on highly refined mineral oils and carefully chosen additives. They are intended for thelubrication of rotary and reciprocating compressors.

APPLICATIONS
Aircol PD are ashless oils recommended for the lubrication of rotors, bearings and gears in rotary compressors, especially oil flooded screw types with delivery temperatures of up to120°C

Aircol PD compressor oils exhibit low carbon forming tendencies and meet the requirements of the DIN 51506 VD-L classificationfor reciprocating compressors having air discharge temperaturesup to 220°C.Aircol PD 32 and 46 are suitable for oil flooded rotary compressors, whilst Aircol PD 68 and 100 would be selected for lubricating the crankcase and cylinders of reciprocating compressors.

Aircol PD 150 is recommended for sliding vane compressors, or for reciprocating units operating at high ambient temperatures. Selection of the required viscosity grade should be based upon the compressor manufacturers’ recommendation. The Aircol PD range is fully compatible with nitrile, silicone and fluropolymer seal materials. Aircol PD is classified as follows: DIN 51506 VD-L. ISO 6743-3 Compressor Oils: DAA and DAB for reciprocating air compressors. DAG for rotary air compressors.

FEATURES/BENEFITS

• Good viscosity characteristics over a wide range.
• Excellent water separation characteristics allows condensation toreadily separate from the oil, minimising the risk of emulsions which could block the oil separator element.
• Prevents corrosion when operating under humid conditions.Excellent coalescing properties means little carry over of oil in the air stream.
• Low deposit forming tendencies extends oil change intervals andprovides longer air filter life which contributes to a reduction in maintenance costs.
• Good thermal stability, low volatility and low carbon formation reduces the risk of fire and explosion.
